If you need Adobe products i would recomend staying on windows. Unfortunetly geting anything Abobe to work is extremly hard, so unless you want to spend hours getting photoshop just for it to break on the next update then its probably not a good idea to switch. The other stuff you listed shoud work fine.

Read Free Software, Free Society by Richard Stallman if you want a material analysis of why GNU/Linux is the way it is today. This is not any attempt at an excuse for limitation, but an explanation for why it exists.

In short, GNU/Linux is pragmatically incapable of running proprietary software. Things like Valve's "Steam" have to be injected into the system as a ready made program. Companies like Adobe (far from your humble starved artist) don't even bother.

You'll run into a lot of problems with GNU/Linux that you'll need to have the confidence to solve yourself. There is no widely-accepted standard to how much computer science an average person should know. Corporate execs prefer you understood nothing while free software advocates want you to know as much as you can. If you don't have a good attitude, you won't get far in GNU.

If you want to kick-start your GNU/Linux journey, use Linux Mint or POP!_OS because if those two can't work on your hardware, then likely nothing else will. Just learn, learn, and don't stop learning.

Well Photoshop is a pain in the ass no matter what platform your on. Everything else should be fine.

• Photoshop: Find an alternative. I see Photopea and Krita brought up quite often.
• Streaming services: Netflix is capped at 1080p, others 720p. Local files should play fine. There is no HDR support.
